Skin Diseases and Disorders01:23

Skin Diseases and Disorders

4.7K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

371
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Psychological and Sociocultural Causes of Schizophrenia

309
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Asthma-II: Pathophysiology and Classification

3.6K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Autoimmune Disorders01:29

Autoimmune Disorders

1.1K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

150
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Area of Science:

  • Rheumatology
  • Immunology
  • Epidemiology

Background:

  • Systemic sclerosis (scleroderma, SSc) is a rare autoimmune disorder affecting multiple organs.
  • Key features include autoantibodies, vasculopathy, and fibrosis.

Purpose of the Study:

  • To review and summarize recent epidemiological studies on systemic sclerosis.
  • To understand global prevalence and risk factors.

Main Methods:

  • Review of recent epidemiological research on systemic sclerosis.
  • Analysis of global prevalence data and demographic variations.

Main Results:

  • SSc prevalence is higher in European, North, and South American populations compared to East Asians.
  • Indigenous peoples in Canada show the highest prevalence (47/100,000).
  • Age, sex, and socioeconomic status (low income) significantly influence SSc presentation, severity, and mortality risk.

Conclusions:

  • Epidemiological insights aid in SSc patient classification, prognostication, and monitoring.
  • Future research should focus on personalized care, targeted screening, and identifying treatment-responsive patient subsets.
